If you are not trading momentum as one of the strategies ask yourself why?
Unless you are living in a cave , you would have seen research on stock market.
In every research on stocks behavior , time and again it has been shown that the most persistent phenomenon is momentum.
Short term trading is about building your strategy around what works in the market not what you "think" or "believe" should work in the market.
If every research shows that momentum works, then you better have very good reason for not trading momentum.
